I had something similar to that on my MacBook and ended up giving up on it. I frequently ended up tripping a soft-fuse or something and the port would stop working until I either put the MacBook to sleep or shut it down (I forget which). Once it started back up, the port worked again.

It was nice to have a "mag-safe" USB-C, but frustrating to have the port stop charging randomly - something I always ended up noticing when my laptop throttled down to a crawl as it reached near-0% battery.
